The Nonindigenous Aquatic Species Flood and Storm Tracker (FaST)
Storm-related flooding can lead to the potential spread of nonindigenous (or non-native) aquatic species into waterways they have not been seen in before. The USGS Nonindigenous Aquatic Species program has developed an innovative mapping tool to help natural resource managers with post-storm nonindigenous aquatic species detection and assessment efforts.
A Structured Decision-Making Framework for Controlling, Monitoring, and Containment of Invasive Species through Trapping: An Application to the Argentine Black and White Tegu
USGS is applying decision analysis to identify cost-effective methods for controlling invasive species like the Argentine black and white tegu.
Fish Slam November 2018
In November 2018, USGS researchers joined partners in South Florida where they sampled freshwater bodies for non-native fishes. The bi-annual Fish Slam event helps monitor new introductions and document range expansion of known non-native fishes.
Development of a Quantitative Risk Assessment Tool to Predict Invasiveness of Non-native Freshwater Fishes in Everglades National Park
The introduction of non-native fishes is a problem across the United States, particularly in Florida. USGS scientists are developing a decision support tool to help natural resourece managers prioritize which species to focus prevention, detection, rapid response, and control efforts.
Risk Analysis of Invasive Freshwater Fishes in Hawaii and Micronesia
Invasive species threaten biodiversity around the world, especially on islands. USGS scientists are helping to identify fish species that have the greatest potential to invade the fresh waters of Microneisa.
WFRC Ecology Section - Projects Overview
The Ecology Section examines how environmental variability, human activities and infrastructure influence food web interactions and species performance in freshwater and marine ecosystems. We have extensive experience in quantifying aquatic food web processes as they relate to growth, survival and production of key species of interest, especially resident and anadromous salmonids.
Species Studied by the Western Fisheries Research Center
Many species are studied at the Western Fisheries Research Center. These species include bacteria, birds, fish, invertebrates, parasites, plants, and viruses. The list contains both common and scientific names, and where each are being studied on the WFRC landscape.
BOR environmental DNA sampling for invasive mussels at USGS gages
As part of an ongoing project funded by the Bureau of Reclamation and lead by the Idaho Water Sciences Center (IDWSC) and Northern Rocky Mountain Research Center (NOROCK), the Upper Midwest Environmental Sciences Center (UMESC) will analyze environmental DNA samples collected at gage stations directly downstream of multiple reservoirs throughout the Columbia River Basin. The goal of this project...
Monitoring Bird and Rat Behavior to Improve Invasive Species Management
Introduced rats are notorious predators of birds and their nests worldwide, but especially on remote islands. Rats ( Rattus exulans ) first arrived in Hawai‘i with Polynesian colonists about 1,000 years ago, resulting in deleterious consequences for native birds and ecosystems. Since Western contact in 1778, two additional rat species have become established in Hawai‘i, including the highly...
Invasive Carp Species Section
Bighead carp ( Hypophthalmichthys nobilis ) and the closely related silver carp ( Hypophthalmichthys molitrix ) (together, the bigheaded carps) and black carp ( Mylopharyngodon piceus ) are rapidly expanding in numbers and distribution in the Mississippi and Missouri River basins.
Climate and Management Effects on Soil Infiltration and Runoff in Hawaiian Forests
Hawai‘i's precipitation is greatest in upland areas that are typically forested. This precipitation provides water for both people and ecosystems. Precipitation can either run off and contribute to streamflow, or infiltrate into the ground and provide water for plants, base flow to streams, or recharge to aquifers. The exact routing that water takes is controlled by many factors, including the...
Evaluation of dissolved carbon dioxide (CO2) as a non-physical deterrent to invasive Red Swamp Crayfish (Procambarus clarkii) and Rusty Crayfish (Faxonius rusticus)
Red swamp crayfish ( Procambarus clarkii) and Rusty crayfish ( Faxonius rusticus ) are invasive crayfish species in nearly all Great Lakes states (https://nas.er.usgs.gov/viewer/omap.aspx?SpeciesID=217). Both species are a concern in Michigan because they can displace native crayfish populations, their feeding behavior reduces habitat for amphibians, juvenile fish, invertebrates, and waterfowl...
